Rvt'vrring now to thv svvvrntlgnrvs of thv i drnwings. in most, of whit-h thv fountain-pmi is shown on a vonsitlvrul ly-vnlu rgvii smile, the

vivw, said View showing in plan evt-min hodying the prinviptvs of thc prvxssvnt nnvnL IIO reference character l indicates the usual hollowor tubular holder, which is provided at its forward end with the usual construction of tubular ink-feeding member or device 2, carrying the nib or pen 3.

The reference character 4 indicates a suitable end cap, which may be sli )pcd in the usual manner over either end of t 1e fountainpen, according to the uses of the pen. Any crm of end ca 4 may be used, that shown in Fi s. 1, 2, andp being provided with a suitab e rejection or stud, as 5, or the end cap may e tapered, as at 6 and as clearly indicated in F1g. 8 of the drawings, the purposes of said projection or stud 5 and the tapered portion 6 of the said end caps being presently more fully set forth. Suitabl connect- -ed With the shank 7 of said ink-fee ing member or device2 is the open end 9 of a flexible bulb or bag 8, which is of an elongated form, so as to lie within the interior of the hollow or tubular 'holder 1, substantially as illustratedin Figs. 3, 4, and 5 of the drawings, the rear and closed end portion 10 of .the said bulb or ha 8 terminating near the closed end of said hol er 1 and extending beyond a hole or perforation 11, formed, referably, at a point between said4 closed ens portion 10 and the middle of the penholder 1. Theend portion of the holder 1 is closed by means of a retaining member, plug, or anchor 12, which formed with a diametrically --extending groove or slot 13, normally in allnement with a plane passing throu h the central longitudinal axls of the said older 1 and vertically through the center of the hole or perforation *11 in said holder. Movably arranged upon the outer cylindrical surface of the said bulb or ba 8, longitudinally within the said tubular ho der 1 and extending directly over the said hole or perforation 11, as clearly illustrated in Fig. 4.0i the drawings, isa presser bar or plate 14. The forward end portion 15 of said presser bar or plate terminates, preferably, at a oint substantially near the open .end 9 of the ulb or bag 8, While at its opposite end said presser bar or plate 14 is provided with a rejection or tongue 16, forming, with (i) of said bar or plate, a pair of oii'sets 17, as c early shown in Figs. 3 and 7 of the drawings.4 As shown in said Figs. 3 and 4 the sai rojection or tongue 16 is fitted and is movahle vertically in the diametricallyextending channel, groove, or slot 13 of the lug or anchor 12; ut any lateral gr Wabling motionf the resser bar or plate 14 is full overcome by tle shoulders or offsets 17 oft esaidbar or plate 15 ridinagainst the shown in said 3 of the drawings. prevent any lon tudinal movement of the jpresser-bar 14 within the hollow or tubular edge portions 18vcontiguous to t 'e groove or slot 13 in the lug or anchor 12, as clealrlly 0 penholder 1 and also to prevent the displacement of the said: tongue or projection 16 from said groove or slot 13, the said presserhar 16 is made with a hole or perforation 19, into and through which extends a pin 20, which has its ends suitably secured in the opposite walls of the penholder 1, as clearly shown in Figs. 4 and 5 of the drawings. The said hole or perforation 19 is made slightly larger than the cross-section of the pin 20, whereby the oscillating motions ofthe presserbar 14 in compressing the flexible bulb or bag 8 and in returnin to its normal initial position are not interered with.

From an inspection of Fig; 5 of the drawings it will be seen that when the rojection or stud 5 or the pointed or tapereg end 6 of the cap 4 is inserted in the hole or perforation 11 the presser-bar 14 assumes an angular osition longitudinall within the penholdler 1, as shown, the en ortion of the bar or plate 16 which is provied with the rojection or tongue 16 sliding in the ui ing groove or slot 13 of the plug or anc or 12, while the oppositeA end portion 15 of the presser bar or platen-1 has noV movement, or, 1f any, but a very slight movement. This is due to the erforation or hole 11 lyin back of the midcil pressure which is exerted upon the presser ar or plate 14 is correspondingly brought back ofthe middle or central portion ofthe said bar or plate 14 and causin it to assume the angular osition shown. herincipal purpose of this is that the flexible bu h or bag 8j is compressed from its closed end portion 10 to a point near the front and open neck 9, whereby any air that may be within the bulb or bag 1s forced from the rear to the front of the bulb or bag, and the latter in assuming its normally expanded condition when the pressure is removed from the presser-bar fully taking up by suctio' a maxlmum amount of the ink. Furthermore, owing to the prevention of any lateral as well as any longitudinal movement of the presser bar or late upon the outer surface of the iexible bu b or bag 8, the said bar or plate always l perfectly fiat upon said surface, it wil be seen that there will be no undue chaing or cutting action between the lon 'tudinal edges of the presser bar or late Wit the soft and pliable e of the penholder, where y the r surface of the ulb or bag 8 while being coml pressed.

From the foregoin description vol my present,invention it be clearly seen that I have devised a simple and stron fountainpen provided with a self-filling receiy' and retaining reservoir, which is iexible an may be readily com ressed by the insertion of the end portion o the end cap of the penholder or other rigid piece as the end of a lead-pencil, match, or the lilie, into a efferation in the body of the holder, the hol er having no projectlng partsz which are objectionab e because of the fact of the possibility of catching in the lining of the pocket or perhaps becoming depressed accidentally by pressure when thus 1n the pocket and forcin any ink in the reservoir from the latter an from the pen end of the holder and ruining the garment in the ocket of which the fountain-pen may have een placed.

Having thus described my invention, what I claim is l. n a self-llinghfountain-pen, a tubular holder, said holder aving an opening in its side, a flexible ink-receivin reservoir 1n said holder, a presser-bar in sai holder having an oscillatory motion between themuter face of said reservoir and the o en' in said holder,

and means connected with sai holder for preventing lateral as weil as longitudinal movel and for the u ments of the presser-bar, consisting of a plu having a diametri'oally-dis osed channel, an a ton e on said presserar extending into said c annel and provided with offsets bearing upon the edge portions of said plug contiguous to the said channel, substantially as ses set forth. 2. in a se fling fountain-pen, the combination, with a tubular holder, provided in its side wlth an opening, of an end cap detachably connecte wit said holder, a flexible ink receiving reservoir in said holder, a presser-har in said holder between the outer surface of said reservoir and the opening in said holder, and means on said end cap ada ted to be inserted in the opening of said hol er for producing an oscillatory motion of the presser-bar and a compression of said reservoir, and means connected with said holder for preventing lateral as Well as longitudinal movements o the presser-bar, consisting of a plug having a diametrieally-disposed channel, and a ton e on said presser-bar extending into said c annel and provided with oil'- sets bearing upon the ed e ortions of said` plu contiguous to the sai c nnel, substantial y as and for the purposes set forth.

3. The herein-described fountain-pen cornprisin a tubular body havin an opening in its si e, for the rece tion o a compressing means, a flexible in -receivin reservoir in said holder, a plu in said ho der provided with a diametricsly-xtending channel, a

resser-bar arranged between the outer surace of said reservoir and the opening in said holder, and a tongue on said presser-bar extendin into the channel-of said plug, substantia ly as and for the purposes set forth.

The herein-described fountain-pen com. rising a tubular body having an opening in its side for the rece tion of a compressing means, s. flexible in -receiving reservoir in said holder, a lug in said holder provided with a diametrieal y-extendin channel, a presserbar arranged between t e outer surface of said reservoir and the opening in said holder, and a ton e on said resser-bar extending into the c annel of sai plug, and means for reventing lateral movement of said presserar comprising offsets on opposite sides oi said tongue in engagement wit the ed e portions contiguous to the channel in sai p ug, substantie y' as and for the purposes set forth.

5. The herein-described fountain-pen comrisin a tubular body having an opening in its si e for the rece tion of a compressing means, a flexible in -receivin reservoir in said holder, a plu in said ho der provided with a diametrica l -extendin channel, a resser-bar arrange between t e outer surace of said reservoir and the opening in said holder, and a tongue on said presser-har extending into the channel of said plug, and means for preventing lateral movement of said resser-bar, comprising offsets on opposite sides of said tongue in engagement with the ed e ortions contiguous to the channel in sai said presser-bar being further provide with a hole, and a pin secured at its ends to said holder and extending through the hole in said presser-bar to prevent lon itudinal movement of said presser-bar, su

stantially as and for the purposes set forth.

In testimon that I claim the invention rset forth above l ave hereunto sot my hand this 6th day of September, 1905.
